Seongjeonggak Hall in Changdeokgung Palace, although built after the Japanese Invasion in 1592, displays the architectural style and structure of Early Joseon period. It did not include ondol (Korean floor heating system) and contained Early Joseon style window frames. Later, King Jeongjo installed ondol as he repaired the building into a more convenient office. The initial construction of Seongjeonggak Hall was based on the architectural ideology of the Early Joseon Period, which divided up the space according to the season. Thus, the initial structure of the building consisted of a joint of a one-story building and a two-story building with the top floor of the latter specialized for hot and humid season. The two-story building was called 'chimnu(寢樓)', and its top floor was called 'nu-chimsil(樓寢室)'.

In Korea, the occurrence and risk of similar fires are high, so setting up fire prevention measures through fire case investigation is considered the most basic measure in securing human safety. Therefore, the purpose of this study is to research status and related regulations of Life Safety Codes for High Fire Risk Building Applications In the future, using this as basic data, it is considered that additional research is need to development Human Safety Standards in Korea.

We need the contingency cost in order to deal with the uncertainty to be accompanied inevitably at the construction and an every kind risk not to forecast in advance. And also the contingency colt needed for the change order and we need it for reduction of the delay and reduce the trouble between owner and constructor. This study, through checking and analyzing the risk factor, in the step of domestic construction, suggests optimal management reserve to specific business about the contract type and the scale. The main results of this research are summarized as follow. First, I investigated the recognition about the contingency cost, grasped the risk to be happened at the construction step and found out the frequency occurrence, through making up question to engineer are carrying out their job in the domestic construction. Second, I computed optimal contingency cost rate by the statistics investigation, and proposed an improvement plan and problem when compute a contingency cost.

Lately Construction industry has been depressing by hard construction market circumstance. Construction company, especial at this time, makes more rationalize the management of inside Company and Construction field. In this study we are to present the method of calculation reasonable duration at Reinforced Concrete Work. For the study first make up a question at field workers, then sampling the Form workers based the question. Second, We are using Work Analysis Method analysing the worker's work-method and Time. And then using the result of analysis, measure the Productivity of Form work. The productivity of Form work is used the basic data of duration at Reinforced Concrete Work

The construction industry in recent years, due to the multi-species engineering specialty, interest and importance of human resource management is growing. But, not many studies on the operation ratio are being proceeded due to the difficulty of casting people on site and actual survey. Thus, this study proposes the work type-specific quantitative operation ratio through work type-specific operation ratio analysis of reinforced concrete construction which takes up an important part of construction work.

These days, the extension and complication of construction project has attached greater significance to IT system for effective project management. Construction companies inside the country have established IT system, but the fact is that they are not up to the expectations of investment provision, and the absense of objective and strategy about project management information system makes its efficiency doubtful. The research, from the point view of construction company, makes an estimate of indefinite future, and presents the process of making out IT system roadmap as a long-term strategy in building IT system.

This paper proposes a process to calculate the amount of construction and demolition (C&D) of underground vertical extension methods through considering the characteristics of used construction and demolished materials. The underground vertical extension methods analyzed in this paper were the bottom-up, normal top-down, and top-down methods with multi-post downward (MPD). In order to check the applicability of the proposed process, 24 illustrative examples were generated. The amount of C&D waste of the illustrative examples were calculated and compared. As the results, the top-down method with MPD was the most efficient method to reduce the amount of C&D waste.

한국은 건물부문 온실가스 감축 목표 달성을 위한 핵심정책으로 2020년부터 공공부문 신축 건축물을 대상으로 제로에너지건축물 인증 의무화를 시행하였다. 이 논문은 제로에너지건축물을 활성화 시키고자 하는 정책 환경에서 건축 관계자들이 제로에너지건축 구현에 의사결정을 위해 참조할 수 있는 에너지절감 기술과 경제성 요인을 제시하는 것이 목적이다. 본 연구를 위해 최근 3년간 건축물 에너지효율등급 인증 자료와 공공기관을 대상으로 공사비 세부 내역서 자료를 수집하여 건축물 에너지 항목에 대한 공사비를 분석하였다. 또한, 건축물 에너지효율등급 인증 자료를 바탕으로 베이스라인 건축물의 각 에너지항목별 에너지성능을 도출하였으며, 베이스라인 건축물의 에너지항목에 대해 단계적으로 에너지성능 값을 상승을 시키는 반복적 시뮬레이션을 통해 제로에너지건축물의 에너지항목별 에너지성능 값을 도출하였다. 최종적으로 도출된 베이스라인 건축물과 제로에너지건축물의 에너지성능 값에 조사된 에너지항목별 공사비를 적용하여, 베이스라인 건축물과 제로에너지건축물의 에너지항목별 공사비를 도출하였다. 그 결과 제로에너지건축물을 구현하는 데 조명설비가 10.5%로 에너지절감에 가장 큰 기여를 하며, 냉·난방 시스템의 공사비 증가분이 9.1%로 가장 작은 것으로 분석되었다.
